All the ia64 pvops code is now dead code since both
xen and kvm support have been ripped out [0] [1]. Just
that no one had troubled to rip this stuff out. The only
useful remaining pieces were the old pvops docs but that
was recently also generalized and moved out from ia64 [2].
This has been run time tested on an ia64 Madison system.

commit 93f378883cecb9dcb2cf5b51d9d24175906659da
"Fix ia64 build errors (fallout from system.h disintegration)"
introduced arch/ia64/include/asm/cmpxchg.h as a temporary
build fix and stated:
"... leave the migration of xchg() and cmpxchg() to this new
header file for a future patch."
Migrate the appropriate chunks from asm/intrinsics.h and fix
the whitespace issues in the migrated chunk.

implement binary patching optimization for pv_cpu_ops.
With this optimization, indirect call for pv_cpu_ops methods can be
converted into inline execution or direct call.

pv_cpu_ops.getreg(_IA64_REG_IP) returned constant.
But the returned ip valued should be the one in the caller, not of the callee.
This patch fixes that.

After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.
